Ah.
Not so much a tagging issue .. a 'style' issue.
Is there a gittyhub talk group?
You could take the data and loacly convert the ref value to include th
emax speed value ..
for your example
ref=Ak9
maxspeed=30 (mph .. stored in kmh so you will need a conversion for mph
to
ref=Ak9)(30 mph
mexspeed=30
...
That may then render the way you want it. Bit of a work around, would be
easier with direct coding.
